I have some customers in your position in my area and I keep an old laptop around that runs Windows 98 and the PanelBuilder 1200 and 1400e software packages. I keep that because the PB1400e is pretty creaky and doesn't play very well with some post-NT software and OS combinations. The cables are all in the box with it and we haul it out a couple of times per year.
The only charge I have is that they give me the original program and let me quote conversion to RSView ME for when the original CRT terminal eventually fails.
If you have a good relationship with your local RA office you can probably swing a similar deal.
